Abstract: For the defect of merely considering the randomness and fuzziness in the process of traditional quantifying qualitative concept, cloud model is used as the quantitative tool of linguistic evaluation terms from two aspects of randomness and fuzziness, and then integrate the evaluation information of experts. For the defect of traditional diversity measurement between cloud models, the distance measure algorithm of cloud model is proposed from the angle of cloud drops distribution, then the similarity measure algorithm of cloud model is proposed. Considering the mutual influence relationships among decision criteria, cloud model and Decision-Making Trial and Evaluation Laboratory（DEMATEL） are combined, and cloud-DEMATEL is used to analyze and amend the initial importance degrees of decision criteria, then calculate the criteria weight. Cloud distance measure algorithm is used to calculate distance from the scheme to positive and negative ideal solution, and then cloud-VIKOR is used to get the compromise optimal solution of alternatives. Finally, an application example is given out to demonstrate the feasibility and effectiveness of the proposed approach.
